1. Cut the blade from the bottom of the chip before entering, and then cut the base into oblique holes with a sharp knife. The incision should be smooth and absorb water and nutrients. Change the water every 3-4 days. Do not move or change direction for 10 days. Silver-white fiber roots can grow in about 15 days.

In spring and autumn, L compound fertilizer can be used every month. According to the data, bamboo is rich in water and precious.
